My money's on the battery being toast.  I wonder why?  My guess is that the 
battery has been cycling through low and high charge states because of a 
clandestine current consumer somewhere, and has now finally given up.  
Batteries will only tolerate a certain number of really deep discharge and 
recharge cycles - must of the time, they stay pretty close to fully charged.

this appears to work - beware!  It's probably only fixed the symptoms and not 
what caused them by killing your old battery.  Find that current consumer.
